@@JustLikeASteam There is a mistake related to the normality of Na2CO3 it's actually 0.05 and 1.325 in 500 ml. For whole video thank you. these changes must be acknowledged.
Hello, I also need a video for acidity and hardness based on APHA, AWWA, and WEF. By the way, in the 23rd Edition of Standard Methods for the Examination of Water and Wastewater from APHA, AWWA and WEF, they also use other indicators like bromcresol green (I don't know why) and other things. Are there any videos available that explain acidity and hardness according tho those standards?

To prepare 0.05N sodium carbonate we need to add 1.325 g in 500 mL of distilled water not 2.65 g of sodium carbonate.
Can you tell how to make standard for estimation of nitrate and phosphate
Sir sodium carbonate N is 0.005 or 0.05??? You have said 2 values in d video
Sir can you tell me how to correlate physicochemical parameters verses biotic communities
Sir can u pls upload video for COD and chloride
Fantastic video. Cleared all my doubts.
I'm so happy to know when my intention of helping others is let known. Thank you so much. It greatly appreciated 🙏
Thank you Can you share the excel sheet sir?
Thank you very much Sir for this video. Please can you upload video on Estimation of Acidity in water.
Really grateful 🙏. Ok and thank you so much again. Thanks a lot
Would it be permissible according to those standards to just keep working with 0.1N of sulfuric acid?
How do I calculate the total alkalinity when phenolpthalein and methyl orange
It's is there in the calculation part of the video. Kindly watch the video again 🙏 ☺️ Thank you 😊 🙏

This method is based on which standard method? Could you give me references please?

It's mentioned and provided in the video ok. Thank you hope it helps you 😊
Why we not use bromocresol green??
I believe it not in the prescribed procedure adopted. Thank you 😊
